Help please:
I have a qmail server behind a firewall. Supposedly, the firewall is
routing port 25 to qmail server. I know that it does work for the ftp &
http. So, theoretically it should for port 25 as well unless something
really strange is going on. I can send client to client behind the
firewall all day long without a hitch. I can send to clients on the
internet without a problem. However, clients on the internet can't send
back to the clients behind the firewall. No client on the internet has a
qmail account on the server & at this point should not.
This is the error that a friend on the internet is getting when
attempting to send me email.
554 [EMAIL PROTECTED] Recipient address rejected: Relay access
denied.
It is interesting to note that the log files never show the email ever
even gets to the server because no log entry exists to show that an email
was rejected.
Who it is addressed to is asalford & certainly has a useable account on
the server that does work locally. I supposedly have all the right info
in the rcpthosts, locals, tcp.smtp, & me files with all the right the
right entries.
It is possible that my ISP has port 25 blocked but, how do I find this
out? I need some diagnostic techniques that would assist me in figuring
out what is wrong.
Thanks,
Andy
